This study focuses on patients with platinum-sensitive recurrent ovarian cancer. The research evaluates two treatment approaches as maintenance therapy after chemotherapy. The first treatment uses a cancer vaccine called TEDOPI (also known as OSE2101) alone, while the second approach combines TEDOPI with pembrolizumab (also known as KEYTRUDA). These treatments will be compared to standard supportive care.
The main purpose is to determine how effective these maintenance treatments are in preventing cancer progression in patients who have responded to platinum-based chemotherapy. The study will last up to 24 months, during which patients may receive either TEDOPI as an injection under the skin, pembrolizumab as an infusion into a vein, a combination of both treatments, or supportive care.
TEDOPI is a type of treatment called a cancer vaccine that helps the body’s immune system fight cancer cells. Pembrolizumab is a medication that works by helping the immune system detect and attack cancer cells. Both treatments are designed to strengthen the body’s natural defenses against cancer.
